You've got about 10 hours left at the time of this posting to play the Dragon's Hoard Gacha. Tonight it will be leaving and the Forest Butterfly Gacha will take its place. The Forest Butterfly Gacha is the very first Gacha to have a new feature called Complete Gacha. If you complete the Gacha (You do not have to complete the Ladder Rewards) you will receive an extra gift. In this case, the item you will receive is the Forest Butterfly Flapping Wings. This is just a bonus reward similar to the Ladder Rewards, it doesn't take or cost anything from you. Not all Gacha's will have Complete Gacha rewards. Keep an eye on gacha announcements to know when one is available.
Vicky's Shop has updated like everything else in his shop these items are only available for FUNS.
